SELF-OILING JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 873,283, dated November 15, 1887'.

Application filed August 13, 1887.

To aZZ whom it may concern:

Be it known that I, MICHAEL GARLAND, of

Michigan, have invented a new and useful Improvement in Self-Oiliug Journal-Boxes; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this application.

My invention relates to that type or class'of self-oiling journal-boxes or pillow-blocks in which thelnbricant material is fed, as the exigencies of the case may require, through the medium of a wick or wicks, which operate by capillary attraction to convey the necessary quantity of oil from some suitable receptacle within the pillow-block to the periphery of the journal or shaft, which works Within the box of said block. Heretofore several contrivauces have been devised involving this general principle of construction; but in all of them the oil-receptacle has been located either above or below the journal or shaft, and the contrivances have been such as to involve more orless complexity of structure and inefficiency or unreliability of action.

I propose to provide for use an automatic or self oilingjournalbox'which shall be extremely simple of Construction and at the same time perfectly efficient and reliable in its operation; and to this end and object my invention consists in the novel construction of selfoilingbox hereinafter more fully described, and more particularly pointed out and dis tinctly defined in the claim of this specifica tion.

To enable those skilled in the art to which my invention relates to understand and practice the same, Iwill now proceed to more fully describe it, referring by letters to the accom panying' drawings, which form part of this specification, and in which I have shown my invention carried out in that form in which I have so far successfully practiced it, and which is about the best form now known to me.

In the drawings, Figure 1 is an end view or elevation of pillow-block and shaft or journal made according to my invention. Fig. 2 is a top view of the same. Fig. 3 is a-view looking down on top of the contrivance, but with the cap or upper half of the box removed.

Serial No. 246,889. (No model.)

Fig. 4 is a vertical cross-section of Fig. 2.

In the several figures the same parts will be found designated by the same letters of referonce.

a is the lower half or main portion of the pillow-block or box-casting, which may be made in about theform and of about the proportion shown, and which is supposed to be securely bolted onto its supporting surface or foundation by means of suitable bolts, b, in about the usual manner, while a represents the cap or upper half of the box or pillow-block, which, when in place, is secured or held in the usual manner by means of anchor-bolts c, which are inserted within the lower half or base, a, of the pillow-block, and are provided at their upper ends with the usual nuts, d, all as clearly shown.

E represents part of a shaft orjournal that is arranged to run in the journal-box, which latter, as usual, has the two halves a and a provided with the usual Babbitt metalor other bearings, (shownat e.) These Babbitt metals or half-bearings, which are, as usual, cast in the iron halves of the pillow-block or box proper, instead of being held in place by means of anchorages formed'by chiseling r'eat the line was .cesses or depressions in the cast-iron parts and then running the Babbitt metal into such depressions, are securely held in place by anchorages composed of portions of the Babbitt metal, which are cast or run into pockets or depressions a, that are formed in the cast-iron parts in the casting of the latter. The shape and locations of these anchorage pockets or depressions a are clearly shown in the drawings.

At each side oi the journal and within the casting a, composing the main or lower part of the pillow-block, are formed oil chambers or receptacles a", which are separated, as seen, from the Babbitt-metal bearings e by thin partition-like portionsf of the casting a, which partition-likeportionsf of said casting are perforated each with two holes, through which the piece of wick a passes in the manner shown,

the said wick having its uppermost straight portion arranged to lie in contact'with the greater part of the bearing-surface of the journal E and its drooping and outwardly-projecting portion hanging down Within the oil cham- ICC bers or receptacles a in such manner that by lary feeders a each of which has its body porcapillary attraction the oil or other lubricant tiou arranged within a longitudinal recess in in said chambers will be continually fed by the bearing and in contact with the shaft or said wicks to the bearing-surface of thcjourjournal, and also has its ends depending into 5 nal Ejnst in proportion as said journal may one of said oil-receptacles, all as hereinbefore I5 require lubrication. set forth.

\Vhat I claim as new, and desire to secure by MICHAEL GARLAND. Letters Patent, :is- \Vitnesses:

A journal-box having oil-receptacles a, ar- W. J. MCCORMICK, xo rangedas specified, and provided with capil- WM. E. TAPERT.
